Product description
Heat shrink tube for battery cells and battery packs. Used to insulate and protect assembled battery packs. Provides a durable and secure outer layer that keeps the cells in place while ensuring electrical insulation and mechanical protection. The material shrinks tightly around the battery pack when heated, giving a clean and professional appearance.
Heat shrink tube is commonly used for battery packs built from AA, AAA, 18650, and 21700 cells. It helps prevent short circuits, protects against dust and moisture, and increases mechanical stability during handling and use of the finished battery pack.
